Anyone notice how dirty the back of the car gets when it rains? I mean it is filthy. The rest of the car doesn't get nearly as dirty. I'm sure it's from the road spray, but I'm not sure what to do about it. Do the oem splashguards work well? I was thinking about getting them to help with this issue. Any thoughts?

 

It's down draft from your rear spoiler not much can be done about unfortunately

 

I doubt you will be able to do anything about it. It is typical for most cars for the rear to get dirty in the rain. The rear will get dirtier than the rest of the car without the rain. With the rear exhaust and short over hang on the Mini it is probably worse.

 

Make sure the back has a nice coat of wax, it will be much easier to wash...

 

It's just a MINI design feature... You'll especially see this when you open the boot and inspect the wells that accommodate the boot hinges. Sometimes I think I could build little sand castles in there...

I tis a good thing. That is a sign of proper air flow dynamics around the car. For instance, my old E36 M3 had more of that rear dirt effect than a standard 3-series because of differences in the aerodynamic bodywork. In that case, the rear diffuser made the difference.

 

I've noticed the same thing. It was clean when I bought it, and it rained that evening, and looked like hell when it dried. I'm not concerned about it, but it can look pretty nasty.

 

There is a reason it has a rear wiper.

 

I tried that...meh, it only does the window.

 

Yeah, didn't think there was much i could do about it. I'm not really concerned just thought I'd throw it out there an ask.

 

I noticed this the other day. The boot of my MINI was filthy and the rest wasn't that bad.

 

The same thing is true of all hatchback designs: the more square-ish the back end, the higher the pressure drop in the airstream behind the body at speed.

That's the reason they add a wiper to the rear windscreen, otherwise you wouldn't be able to see out the back window when it's raining / snowing / otherwise vision-impaired.

Put it up to the price you have to pay for driving something nifty! At least the whole back sides not so large as to make washing it off difficult!

 

The new Teardrop Edition MINI will not have this problem.

Nothing worse than a dirty butt...

It amazed me when i first drove in the rain but it is something you get used to . Just dont try to take off with a wet car on a nice fall day as you will most likely have the entire rear window filled with leaves .

 

its raining in sacramento today and i experienced what you area all talking about... the front and sides of the car looked clean, albeit wet but the back end... my goodness it was nasty. I just rinsed it off when i got home to get all that loose dirt off the car. That way, when it dries, it will look clean!

 

Truer words were never spoken.

 

+1....raining in sac. = rear of car getting dirty.

 

The dirty back is the result of the shockwave created when the car rockets into top gear...Duh!!!

 

It's better than R50/53 was!!!

 

its a problem with most everything that has a high back end. Creates more turbulence at the back which allows the rain to deposit all the dirt on the car. If the flow where laminar the air would be moving smoothly across the car not allowing much to actually touch your car. The turbulent air will create random swirls which transfer all the dirt on the road that got picked up with the rain and sprayed into the air onto to your car. Its a pain, but I hate to think how little space we would have if the mini kept to flow laminar.

 

Yup, I can't wait for the greenhouse back window.

 

hyperbolic chamber is the best thing for the Mini. The only downside is people know clean Minis aren't motoring.

 

Mine's specifically dirty from the flux capacitor option..it gets dirty in the earlier years I visit...
